Unable to validate signatures on document created with DocuSign

Hello,

I have a PDF with digital signatures that was signed with DocuSign. I can validate the signed document and everything looks good when I use https://validator.docusign.com/ However when I open the document with Acrobat Reader DC the signature validation does not succeed, and I'm wondering why. Under the signature I see the following: "Signature is invalid: There are errors in the formatting of information contained in this signature". When I click on validate signature I get the following error message: "Error during signature verification. Error encountered while validating: Internal cryptographic library error. Error Code: 0x2711".

Any ideas on how to investigate the exact cause for the error?

Thanks.

Thanks for your reply Amal. Unfortunately the suggestion to locally install the certificates needed to validate the signer's trust chain did not work. The document I'm validated has two signers: one is a customer that uses a certificate issued by TeleSec PKS eIDAS QES CA 1 and the second is DocuSign. The second signature can be validated but not the first. I'm attaching screenshots so you can see the problem.signature validated.png

This is for the customer signature, issued by TeleSec PKS eIDAS QES CA 1 which has a certification path installed on my local PC.
